Qhov zoo ntawm LED teeb hlaws cuam tshuam rau yim yam ntawm LED zaub
1. Kev xav
Lub kaum sab xis saib ntawm LED zaub nyob ntawm seb lub kaum sab xis ntawm LED teeb hlaws. Tam sim no, feem ntau sab nraum zoov cov ntxaij vab tshaus siv elliptical LEDs nrog kab rov tav saib lub kaum sab xis ntawm 100 degree; thiab ntsug saib lub kaum sab xis ntawm 50 degree; thiab cov ntxaij vab tshaus sab hauv tsev siv SMD LEDs nrog ob qho tib si kab rov tav thiab ntsug ntawm 120 degree. Lub vijtsam zaub ntawm txoj kev loj feem ntau xaiv 30 degree vim nws qhov tshwj xeeb; lub voj voog LED nrog lub kaum sab xis pom yog txaus. Tso rau ntawm qee lub tsev siab xav kom pom cov kaum sab xis siab dua. Lub kaum sab xis saib thiab ci ntsa iab yog qhov tsis sib xws, thiab lub kaum sab xis pom loj yuav ua rau txo qis qhov ci. Kev xaiv lub kaum sab xis yuav tsum tau txiav txim siab raws li kev siv tshwj xeeb.
2. Kev ci ntsa iab
LED ci ntsa iab yog qhov tseem ceeb ntawm kev ua kom pom qhov ci. Qhov siab dua qhov ci ntsa iab ntawm LED, qhov ntau dua cov npoo ntawm qhov siv tam sim no, uas yog qhov zoo rau kev txuag hluav taws xob thiab ua kom lub LED ruaj khov. LEDs muaj lub kaum sab xis sib txawv. Thaum lub ci ci ntawm lub nti yog tsau, lub kaum sab xis me dua, lub teeb ci dua LED, tab sis qhov me dua qhov pom lub kaum sab xis ntawm cov zaub. Feem ntau, 100-degree LED yuav tsum raug xaiv los ua kom pom lub kaum sab xis txaus ntawm cov zaub. Rau cov lus qhia nrog cov ntsiab lus sib txawv thiab qhov sib txawv ntawm qhov pom, qhov sib npaug yuav tsum pom nyob rau hauv qhov ci, lub kaum ntse ntse thiab tus nqi.
3. Tus nqi ua tsis tiav
Txij li thaum cov xim puv xim yog tsim los ntawm kaum tawm txhiab lossis ntau pua txhiab pixels uas muaj peb hom liab, ntsuab thiab xiav LEDs, qhov tsis ua tiav ntawm cov xim LED yuav cuam tshuam rau tag nrho cov kev pom ntawm cov zaub. Feem ntau hais lus, raws li kev lag luam kev paub, qhov ua tsis tiav ntawm LED zaub yuav tsum tsis txhob siab dua 3/10, 000 (hais txog qhov ua tsis tiav los ntawm LED teeb hlaws nws tus kheej) ua ntej LED zaub pib sib sau thiab hnub nyoog rau 72 teev ua ntej khoom xa tuaj.
4. Antistatic muaj peev xwm
LED yog cov khoom siv hluav taws xob semiconductor, uas nkag siab rau hluav taws xob zoo li qub thiab tuaj yeem ua rau hluav taws xob tsis zoo. Yog li ntawd, lub peev xwm los tiv thaiv zoo li qub tseem ceeb heev rau lub neej ntawm lub vijtsam zaub. Feem ntau hais lus, qhov tsis ua hauj lwm voltage ntawm LED tib neeg lub cev electrostatic hom kuaj yuav tsum tsis txhob qis dua 2000V.
5. Lub neej ntev
Lub neej theoretical lub neej ntawm cov khoom siv LED yog 100, 000 teev, uas ntev dua li lub neej ua haujlwm ntawm lwm cov khoom ntawm LED zaub. Yog li ntawd, ntev npaum li qhov zoo ntawm cov cuab yeej LED tau lees paub, qhov kev ua haujlwm tam sim no tsim nyog, PCB tshav kub dissipation tsim tsim nyog, thiab cov txheej txheem tsim khoom yog nruj, cov khoom siv LED yuav yog tag nrho cov zaub screen. Ib qho ntawm cov khoom siv ruaj khov tshaj plaws hauv lub tshuab.
Cov khoom siv LED suav txog 70 feem pua ntawm cov nqi ntawm cov lus qhia LED, yog li cov khoom siv LED tuaj yeem txiav txim siab qhov zoo ntawm LED zaub. kuv lub teb chaws tsis yog tsuas yog tus tsim khoom loj ntawm LED, tab sis kuj yog ib qho chaw sib sau ua ke rau LED zaub ntau lawm. Cov kev xav tau high-tech ntawm LED zaub yog qhov kev txhim kho yav tom ntej. Cov kev xav tau zoo ntawm LED zaub tsis yog tsuas yog hais txog cov qauv ntawm LED cov tuam txhab lag luam, tab sis kuj tseem tsim cov khoom lag luam LED zaub. Los ntawm kev tswj cov khoom siv LED, los txhawb Tuam Tshoj txoj kev hloov pauv los ntawm lub teb chaws loj LED zaub tsim rau lub teb chaws muaj zog LED zaub tsim.
6. Attenuation yam ntxwv
Tom qab LED zaub ua haujlwm ntev, qhov ci ntsa iab yuav poob thiab cov xim ntawm cov zaub yuav tsis sib haum, uas feem ntau tshwm sim los ntawm qhov ci ntsa iab ntawm cov khoom siv LED. Lub attenuation ntawm LED brightness yuav txo qhov ci ntawm tag nrho cov zaub screen. Qhov tsis sib xws ntawm qhov ci ntsa iab ntawm cov xim liab, ntsuab thiab xiav LEDs yuav ua rau qhov tsis sib xws ntawm cov xim ntawm LED zaub, uas yog qhov tshwm sim uas peb feem ntau hais tias cov khoom siv. Cov khoom siv zoo LED tuaj yeem tswj tau qhov loj ntawm qhov ci ntsa iab attenuation. Raws li tus qauv ntawm 20mA teeb pom kev zoo nyob rau hauv chav tsev kub rau 1000 teev, liab attenuation yuav tsum tsawg tshaj li 2 feem pua, thiab xiav thiab ntsuab attenuation yuav tsum tsawg tshaj li 10 feem pua. Yog li ntawd, sim tsis txhob siv 20mA tam sim no rau xiav thiab ntsuab LEDs hauv cov qauv tsim, thiab nws yog qhov zoo tshaj plaws los siv tsuas yog 70 feem pua rau 80 feem pua. feem pua ntawm rated tam sim no. Shenzhen Aurora Optoelectronics siv imported potting silica gel, thiab lub attenuation tuaj yeem ua tiav rau 1000 teev nrog 0 lub teeb attenuation.
Ntxiv rau cov yam ntxwv attenuation muaj feem xyuam rau cov yam ntxwv ntawm cov xim liab, ntsuab thiab xiav LEDs lawv tus kheej, tam sim no siv, lub tshav kub dissipation tsim ntawm PCB pawg thawj coj saib, thiab lub ambient kub ntawm cov zaub screen tag nrho cov cuam tshuam lub attenuation.
7. Loj
Qhov loj ntawm LED ntaus ntawv cuam tshuam rau pixel nrug ntawm LED zaub, uas yog, kev daws teeb meem. 5 hli elliptical teeb yog tsuas yog siv rau sab nraum zoov cov ntxaij vab tshaus saum P16, 3 hli elliptical teeb yog tsuas yog siv rau P12.5, P12, P10 sab nraum zoov cov ntxaij vab tshaus, 3528 hom SMD LEDs mas yog siv rau P6, P8 sab hauv tsev cov ntxaij vab tshaus, 2020 hom SMD LEDs yog siv rau sab hauv tsev zaub xws li P2 thiab P3. Nyob rau hauv qhov tseeb hais tias lub dot pitch tsis hloov, qhov luaj li cas ntawm LED ntaus ntawv nce, uas yuav ua rau kom cov zaub cheeb tsam thiab txo cov graininess. Txawm li cas los xij, vim qhov txo qis ntawm cheeb tsam dub, qhov sib piv yuav raug txo; ntawm qhov tsis sib xws, qhov loj ntawm LED txo qis, uas txo qhov chaw tso saib thiab ua kom cov graininess. , thaj tsam dub nce, nce qhov sib piv.
8. Kev sib raug zoo
Lub vijtsam puv xim yog tsim los ntawm pixels uas muaj ntau yam xim liab, ntsuab, thiab xiav LEDs. Qhov sib xws ntawm qhov ci ntsa iab thiab wavelength ntawm txhua xim LED txiav txim siab qhov ci ci sib xws, qhov sib npaug ntawm cov xim dawb, thiab chromaticity sib xws ntawm tag nrho cov zaub screen. poj niam deev. Feem ntau hais lus, cov chaw tsim khoom lag luam xav tau cov khoom siv los muab cov LEDs nrog lub wavelength ntawm 5nm thiab qhov ci ci ntawm 1: 1.3. Cov ntsuas no tuaj yeem ua tiav los ntawm cov khoom siv los ntawm lub tshuab spectroscopic xim sib cais. Qhov sib xws ntawm voltage feem ntau tsis tas yuav tsum tau. Feem ntau rau cov chaw tsim khoom cov txheej txheem ntau lawm yuav tsum siab dua
